The Siemens SENTRON 5SL4632-6 is a 3P+N miniature circuit breaker rated 32 A with a B tripping characteristic, designed for 400 V AC multi-phase operation and a 10 kA breaking capacity per both EN 60898 and IEC 60947-2.
B curve and breaking capacity — what they mean for the panel
The B characteristic means the magnetic trip operates at 3–5× In, so a 32 A breaker trips instantaneously between 96 A and 160 A. That suits resistive and lighting loads with low inrush — think heating circuits, general socket outlets, or control transformers. Both standards are certified, so the rating holds for IEC and UKCA jurisdictions alike.
Sealable terminals allow the installer to lock the cover screws after commissioning, preventing tamper.
Power loss per pole is 2.7 W at rated current in hot operating state, so the 3P+N unit dissipates roughly 10.8 W total. In a densely populated enclosure, that heat adds up — account for it in the thermal budget.
